Formula of Clockwise Rotation Calculator

To understand the functionality of the Clockwise Rotation Calculator, it’s essential to grasp the mathematical formula it employs:

x' = x*cos(theta) + y*sin(theta) y' = -x*sin(theta) + y*cos(theta)

  • x, y are the coordinates of the original point.
  • x', y' are the coordinates of the point after rotation.
  • theta is the angle of rotation in radians. Convert from degrees if necessary using theta = degrees * (pi / 180).

This formula is the cornerstone of the calculator’s functionality, ensuring that users can obtain accurate results swiftly.

Example of Clockwise Rotation Calculator

Let’s illustrate the use of the Clockwise Rotation Calculator with a practical example:

Consider a point A with coordinates (2,3) that needs to be rotated 45 degrees clockwise around the origin. Using the formula:

  • Convert 45 degrees to radians: 45 * (π / 180) = π / 4
  • Apply the formula:
    • x’ = 2cos(π / 4) + 3sin(π / 4)
    • y’ = -2sin(π / 4) + 3cos(π / 4)

Most Common FAQs

Q1: Can I rotate a point counterclockwise using this calculator?

A1: Yes, to rotate a point counterclockwise, you would input a negative angle or adjust the formula to reflect counterclockwise rotation principles.

Q2: How do I convert degrees to radians?

A2: To convert degrees to radians, use the conversion formula: radians = degrees * (π / 180). This step is crucial for accurate calculations.

Q3: Is this calculator only for points around the origin?

A3: While most straightforward applications involve rotation around the origin, adjustments can be made to rotate points around any fixed point. The principles remain the same. But the coordinates will need to be adjusted relative to the new center of rotation.
